Re: [Xen-users] blktap2 and qcow2 images

[Sebastian Unger <sebunger44@xxxxxxxxx>]

Mhmm, I've run a quick test, but it doesn't work with qcow either. Although the error is slightly different:

tap-ctl: tap-err:tap_ctl_open: open failed, err -38

Do you know what that error (-38) means?

Out of curiosity, does qcow support in-file snapshots like qcow2?

Cheers,
Seb

I've only used RAW and VHD so far. tools/blktap2/drivers/tapdisk-disktype.c says that qcow, ram, block_cache, vhd_index, log, and remus are also supported. Apart from qcow, I don't know about the rest.
